• Low Distortion, Class A/B Output Stage
• Approved to DESC Drawing 5962-90828
DESCRIPTION
The OMA511 series is a high voltage, high current power operational amplifier
designed to drive a wide variety of resistive and reactive loads. Its complimentary
class A/B output stage provides superior performance in applications requiring
freedom from cross over distortion. This hybrid is housed in a variety of isolated
hermetic packages and is ideally suited for critical environments and is approved to
DESC drawing 5962-90828.

The safe operating area plot
provides a comprehensive summary
of the power handling limitations of a
power amplifier, including maximum
current, voltage and power as well as
the secondary breakdown region. It
shows the allowable output current
as a function of the power supply to
output voltage differential (voltage
across the conducting power device).
